Fingerprint Reader Maintenance
It is very important that the sensor surface is kept clean. If the sensor is dirty
or scratched, there is an increased risk that a fingerprint can not be successfully matched
with its corresponding template stored in the database.
• Protect the fingerprint reader from any kind of physical damage.
• If necessary, clean the surface with a clean cotton cloth. You can dampen the
cloth slightly with a cleaner.
• Do not use paper tissue for cleaning purposes, since it may scratch the surface.
• Do not spray cleaner directly onto the fingerprint reader.
